'Version lines' updated only...

[Alex Clarke]

I'm just upgrading from 1.3.7 to 1.3.7.1. I've decided to compare my original installation with the 1.3.7.1 (this helps me to clean up any core code I've accidently modified!).

Anyway... I've noticed that certain files that contain differences only have a different 'version line'.

By 'version line' (I'm not sure what they're meant to be called) I mean something like this...

* @version $Id: ipn_application_top.php 6528 2007-06-25 23:25:27Z drbyte $

One file I've noticed this with is includes\modules\payment\paypal\paypal_admin_notification.php.

Is there any reason for such lines being different, but no code within the files being different?

A minor question, I know. I'm just curious! :)

There are a few possible causes of that:

1. You've done an upgrade previously and perhaps had your WinMerge or other comparison program set to ignore the version-id lines ... and thus when you merged the new changes into your files, the version info was missed.
(This is the most common).

2. Perhaps you installed some patched files (perhaps the PayPal patch) and that brought the "content" up to date, but when the new version ZIP file was prepared, the code-mgmt tools updated those patched files with a new revision. However, since you already had the updated "code", the only difference you see is the date/time/rev stamp.

3. Perhaps the developers touched a file and maybe decided to "back out" of a change before releasing the new code. The new version stamp info would still appear in the file, even if nothing else was changed in the end.

2 and 3 sound right, I think, as the previous install was 1.3.7 (fresh), but I did apply the xss patch.

Anyway... thanks for the reply. I now know a little bit more about Zen Cart! :)
